I think this has to work this way due to the way polkit/udev, etc.. provide user
hardware access while there are no limitation on root access to hardware devices
(this is the nitty-gritty where my eyes start crossing...) I'll check further
and see if I can confirm the exact differences. (this may be part of the reason
root login is discouraged -- I don't know)

I'll check on real hardware, but that should not be an issue since here sound is
working on vbox. It shouldn't matter to TDE, since it is just a matter of sound
calls being made to moduleX. As long as it is activating/calling moduleX
correctly, then sound should play. Since sound does play in everything except
TDE, it looks suspect. I'll do all the tests you suggested and a real hardware
test. We shall chase it down...
